Add JS backend adapted from the GHCJS project by Luite Stegeman.
Some features haven't been ported or implemented yet. Tests for these
features have been disabled with an associated gitlab ticket.
Bump array submodule
Work funded by IOG.

This patch adds the wasm32-wasi tuple support to various places in the
tree: autoconf, hadrian, ghc-boot and also the compiler. The codegen
logic will come in subsequent commits.

The old name made it confusing why disabling HPC didn't disable the
entire pass. The name makes it clear --- there are other reasons to add
ticks in addition.

With this change, `Backend` becomes an abstract type
(there are no more exposed value constructors).
Decisions that were formerly made by asking "is the
current back end equal to (or different from) this named value
constructor?" are now made by interrogating the back end about
its properties, which are functions exported by `GHC.Driver.Backend`.
There is a description of how to migrate code using `Backend` in the
user guide.
Clients using the GHC API can find a backdoor to access the Backend
datatype in GHC.Driver.Backend.Internal.
Bumps haddock submodule.
Fixes #20927

In which we add a new code generator to the Glasgow Haskell
Compiler. This codegen supports ELF and Mach-O targets, thus covering
Linux, macOS, and BSDs in principle. It was tested only on macOS and
Linux. The NCG follows a similar structure as the other native code
generators we already have, and should therfore be realtively easy to
follow.
It supports most of the features required for a proper native code
generator, but does not claim to be perfect or fully optimised. There
are still opportunities for optimisations.

Update Haddock submodule
|
|
|
* Represent backends with a `Backend` datatype in GHC.Driver.Backend
* Don't detect the default backend to use for the target platform at
compile time in Hadrian/make but at runtime. It makes "Settings"
simpler and it is a step toward making GHC multi-target.
* The latter change also fixes hadrian which has not been updated to
take into account that the NCG now supports AIX and PPC64 (cf
df26b95559fd467abc0a3a4151127c95cb5011b9 and
d3c1dda60d0ec07fc7f593bfd83ec9457dfa7984)
* Also we don't treat iOS specifically anymore (cf
cb4878ffd18a3c70f98bdbb413cd3c4d1f054e1f)
